CVE-2024-43180Network attack vector

Session hijacking via cookies lacking Secure attribute

Published Sep 13, 2024 · Updated Sep 13, 2024

Sensitive-cookie exposure in IBM Concert 1.0 allows attackers to obtain session cookies after a user follows an HTTP link. Authorization-token and session-cookie responses omit the Secure attribute, allowing browsers to transmit those values over cleartext HTTP. Exploitation requires user interaction and network traffic snooping; exposed cookie values permit session hijacking, while integrity and availability impacts are not reported.
